Definitions
- the present invention relates to the use of a sealing sleeve for casting in a wall or floor element.
- the pouring can take place in particular in the course of the production of the wall or floor element, if this is, for example, poured from concrete.
- the sealing sleeve can be mounted on a formwork, then it is structurally integrated into the wall or floor element.
- the potting material typically concrete, thus encloses the sealing sleeve and holds it in position.
- the present invention is based on the technical problem of specifying a particularly advantageous use or a sealing sleeve as the object of use.
- the corresponding sealing sleeve has a potting section and an inverted section, the latter being turned into the potting section during casting. In this turned-in state, the sealing sleeve is axially compact, which, for example, allows a wall or floor element with a comparatively small thickness. After the pouring in, the everting section is turned out, and a tube is pushed into the sealing sleeve through the everted eversion section.
- the pipe In its end position, that is to say in the completely inserted state, the pipe is placed in the sealing sleeve in such a way that one of its two ends is arranged in the sealing sleeve.
- the completely inserted pipe then extends out of the sealing sleeve to its opposite end (this opposite end is arranged outside the sealing sleeve).
- the tube can, for example, be easily inserted and / or fastened into the everted everting section or section.
- the everted everting section can, for example, with a Clamping ring, such as a clamp, can be pressed onto the inserted pipe.
- the potting section is that part of the sealing sleeve that is arranged within the wall or floor element after potting.
- the sealing sleeve can in particular be cast into the wall or floor element in such a way that the potting section extends over its entire thickness. Regardless of this, the potting material rests against an outer wall surface of the potting section, for example, during pouring.
- the everting section is here inversed, it can, for. B. abut against an inner wall surface of the potting section radially opposite the outer wall surface. In this case, the turned-in everted section does not have to extend axially over the entire potting section, compare also the exemplary embodiment for illustration.
- the inserted tube then rests with an outer wall surface on an inner wall surface of the turned-out inverted section, preferably also on an inner wall surface of the potting section.
- the pipe is or is inserted into the potting section, that is to say the end of the pipe is arranged in the end position in the potting section and thus within the wall or floor element.
- the pushed-in end is held radially in position in the wall or floor element (also independently of an additional fastening of the everting section with a clamping ring). This can, for example, accidentally slip out or prevent the pipe from tipping out to the side. If both the inverted section and the potting section each rest on the pipe with an inner wall surface, this can result, for example, in an axially correspondingly large sealing surface between the pipe and the sealing sleeve.
- an inner wall surface of the sealing sleeve rests on the pipe in the axial section into which the pipe is inserted, and the potting material rests on an outer wall surface of the sealing sleeve (for example the concrete); but since the pipe is not pushed through, there is also an axial section in which the inner wall surface does not lie against the pipe.
- axially and “radially” as well as “circumferentially” and the associated directions (axial direction etc.) refer to a central axis of the sealing sleeve, which is located centrally in the through opening delimited by the sealing sleeve.
- the sealing sleeve is or will be cast in a base element, so the center axis is vertical in the installed position.
- this central axis can be angled to the side surface (s) of the wall or floor element, in particular at right angles.
- “Inward” means radially towards this central axis, an inner surface faces the central axis;
- Outward means radially away from the central axis, an outer surface faces away from the central axis.
- the sealing sleeve can, for example, have a web seal, which is arranged in the potting section and rises radially outward with respect to its outer wall surface.
- a bar seal arranged between the axial ends of the potting section, that is to say at a distance from these ends, is advantageous, which is then enclosed by the potting material (which extends or blocks creepage paths along the outer wall surface).
- "Enclosing" means that, viewed in an axial section (section plane includes center axis), potting material is arranged axially on both sides of the bar seal.
- the bar seal can have one or more axial projections, that is to say form a radial undercut with the potting material (which creates a fixation or anchoring).
- the wall or floor element can have a thickness of at most 200 mm, 180 mm, 160 mm, 140 mm, 120 mm, 110 mm, 100 mm or 90 mm.
- Possible lower limits which can also be of interest and should be disclosed independently of an upper limit, can be, for example, at least 50 mm, 60 mm or 70 mm.
- the thickness is 80 mm, for example.
- reduced thicknesses can be advantageous, for example, because of the material savings and, in the case of precast concrete parts, also because of the weight. The thickness is taken perpendicular to the opposite side surfaces of the wall or floor element, between them.
- the radially taken wall thickness of the sealing sleeve can be reduced, for example locally, between the potting section and the eversion section, which can simplify the eversion of the eversion section.
- the sealing sleeve can be designed, for example, as a film hinge between the potting section and the everting section.
- the potting section and the everting section are preferably designed in one piece with one another, that is to say they cannot be separated from one another in a non-destructive manner.
- the two could, for example, also be produced as a multi-component injection-molded part, that is to say, for example, the potting section could be provided from a harder material than the everting section.
- the two are preferably formed monolithically with one another, that is to say from the same, uninterrupted continuous material (without a material boundary in between).
- the everting section preferably also the potting section, can be provided from an elastomer material.
- the “elastomer material” is generally a plastic with elastic behavior. Its Shore hardness (Shore A) can, for example, be at most 90 Shore, 80 Shore, 75 Shore or 70 Shore and (regardless of this) for example at least 20 Shore, 25 Shore, 30 Shore, 35 Shore or 40 Shore . It can be, for example, a rubber material, preferably a synthetic rubber, such as EPDM (ethylene-propylene-diene, M group). But it can be the same For example, it can also be a thermoplastic elastomer (TPE) or a silicone-based material, such as silicone rubber or silicone elastomer.
- TPE thermoplastic elastomer
- the tubular element can, for example, have a Shore hardness (D) of at least 50 Shore, 60 Shore or 70 Shore, with possible upper limits of at most 85 Shore or 80 Shore, at least in the case of plastic.
- the tube is or is pushed into the sealing sleeve up to a stop.
- a projection can also be formed on the outer wall surface of the tube, for example, which then rests against the axial end of the turned-out everted section.
- the stop is preferably formed on the inner wall surface of the sealing sleeve, particularly preferably in its potting section. The stop can be spaced from the two axial ends of the potting section, for example by at least 10%, 20% or 30% of the axial length of the potting section.
- a closure flap is arranged in the sealing sleeve.
- the closure flap can already be arranged in the sealing sleeve when it is poured into the wall or floor element. On the other hand, however, it can also only be used subsequently, i.e. in the sealing sleeve that has already been cast.
- the closure flap can close the passage opening delimited by the sealing sleeve, for example as an odor, vermin and / or foam barrier.
- the flap can, for. B. be molded in one piece or monolithically in the sealing sleeve, but on the other hand it can also be a separate component that is or is inserted into the sealing sleeve. This flap component can, for example, have the flap itself and a flap body on which the flap is mounted. The flap body can form a passage opening which, depending on the flap position, can be closed or released by the flap.
- holding means can be formed on the inner wall surface of the sealing sleeve, which hold the flap component axially in position.
- the flap component can, for example, in a circumferential Be or will be positioned groove.
- the sealing sleeve the material properties of which are selected with regard to good reversibility of the everting section, can also offer advantages in this regard, namely allow easy insertion and removal of the flap component (or other components, see below); it is, for example, also an exchange of the component (s) is possible with a cast-in sealing sleeve.
- the flap can preferably be held in the closed position with force, e.g. B. with appropriate storage of a counterweight or a spring element.
- force e.g. B.
- the spring element can be molded on, or a separate spring element, e.g. B. a spring ring can be used, which presses the flap into the closed position.
- being held in the closed position means that the corresponding force (e.g. spring or weight force) acts on the flap in the direction in which the flap closes.
- the flap is opened, e.g. B. of flowing water.
- the flap can close on the one hand in a direction that points out of the sealing sleeve through the inserted pipe (from the second to the first side of the wall or floor element, see below), the system is then designed for a flow direction from the first to the second side (in this direction the flap opens).
- the flap can also close in a direction pointing over the inserted tube into the sealing sleeve.
- it can represent a backflow flap which opens towards the inserted pipe and closes away from the inserted pipe.
- This system is designed for a flow direction from the second to the first side.
- it can also represent, for example, an odor or vermin seal, in particular when force is applied in the closed position.
- the non-return flap is opened by a flow that is opposite to the second side of the wall or floor element and that of the first side with the everting section is through the sealing sleeve into the inserted pipe.
- the sealing sleeve arrangement can be used, for example, for drainage, that is to say in order to remove water from the second side of the wall or floor element. If, for example, the pipeline system, of which the inserted pipe is a part, is overloaded, a backflow situation occurs, the backflow flap closes and flooding of the second side of the wall or floor element can be prevented.
- a sieve is arranged in the sealing sleeve.
- the sieve could generally be molded in one piece into the sealing sleeve; it is preferably a component that is or will be used separately. Reference is made to the above comments on a “component”; the sieve can, for example, be held in an axially form-fitting manner on holding means formed on the inner wall surface, for example in a circumferential groove. An inserted sieve can be removed if necessary, e.g. for cleaning purposes (of the sieve itself or of the pipeline system).
- a plurality of sieves can also be arranged axially one after the other in the sealing sleeve, for example a coarse sieve for leaves and a fine sieve for small amounts of dirt or debris.
- the coarse screen can, for example, be placed closer to the second side surface than the fine screen (so that it is flowed through first during dewatering).
- the inserted pipe is preferably part of a pipeline system, so it is in turn assembled with a further pipe (on the first side of the wall or floor element).
- the pipe system can preferably be a sewage pipe system, which is particularly preferably used for draining the second side of the wall or floor element (for removing water from there).
- the pipeline system can end in the sealing sleeve. This then forms a drain, and the pipeline system is not extended with an additional pipe on the second side of the wall or floor element.
- an inspection tube is or is attached to the sealing sleeve from the second side of the wall or floor element.
- This can, for example, have a translucent, preferably transparent wall at least in one area and serve to control the water level.
- the pipeline system then preferably ends with the inspection pipe, so no further pipe is attached to this in turn.
- the corresponding sealing sleeve can then be designed, for example, without a backflow flap, so that in a backflow situation the water can rise beyond the sealing sleeve into the inspection pipe.
- B. be equipped with a scale.
- the variant or use of "inspection pipe" can be of particular interest in a drainage system in which several sealing sleeves are used in the manner described here, that is, each form a drain and are connected to the same pipe system. Some of the sealing sleeves can then each be equipped with a backflow flap, but one or more of the sealing sleeves can be provided with an inspection pipe for inspection purposes.
- At least one of the two opposite ends of the sealing sleeve is closed with a lid when pouring in, preferably a lid is inserted into each of the two ends.
- the cover is or will be inserted into the everted everting section, correspondingly it is removed before the eversion.
- the cover can, for example, expose a sieve after being removed, or it can be exchanged for a sieve.
- a one-piece, in particular monolithic, closure formed with the rest of the sealing sleeve could also be provided at one or both ends, which closure is then separated, for example, along a predetermined breaking point.
- a separately inserted cover can, however, be advantageous insofar as it can offer greater stability.
- An inserted lid can be made from an im Compared to the sealing sleeve, it must be made of a harder material, for example reliably closing the sealing sleeve (step protection) or also supporting it during pouring.
- water that is present on the second side of the wall or floor element is discharged through the sealing sleeve.
- This water reaches the inserted pipe via the sealing sleeve and thus, for example, into a sewage pipe system.
- the inserted pipe is used as a water pipe.
- the invention also relates to a sealing sleeve arrangement with a wall or floor element into which a sealing sleeve is cast.
- the sealing sleeve arrangement can in particular have been produced in the course of a method or a use according to one of claims 1 to 10; a tube, for example, can be inserted into the turned-out everted section; express reference is made to the features disclosed above.
- the sealing sleeve arrangement is a precast concrete part.
- B cast in a precast plant and the wall or floor element is transported with the cast sealing sleeve to the construction site.
- the possibility of reducing the thickness of the wall or floor element can be advantageous in that a weight reduction associated with the reduced thickness can, for example, also reduce the effort involved in transport and / or assembly.
- the precast concrete part can generally also be a balcony or terrace element, for example, but it is preferably designed as a light shaft.
- This can, for example, be placed in the ground and set on an outer wall of a building, with a window in the building wall, for example, being able to be arranged in the area of the light shaft.
- the drainage function, and in particular the backwater blocking, can or can be advantageous in that it is one Accumulation of water in the light shaft and thus water entry into the building via the window can be prevented.
- Figure 1 shows a sealing sleeve 1 which is cast in a wall or floor element 2, in the present case a floor element 2 made of concrete. Shown is a partially sectioned side view, the section plane contains a center axis 3 of the sealing sleeve 1.
- the sealing sleeve 1 has a potting section 1a and an inverted section 1b, the latter is in FIG Figure 1 turned into the potting section 1a. In this configuration, the sealing sleeve 1 is encapsulated, which allows a comparatively small overall axial depth.
- the floor element 2 in the present case has a thickness 4 of only around 80 mm.
- the everting section 1b is turned out towards a first side 2.1 of the wall or floor element 2, in the present case downwards.

Description
Die vorliegende Erfindung betrifft die Verwendung einer Dichthülse zum Eingießen in ein Wand- oder Bodenelement.The present invention relates to the use of a sealing sleeve for casting in a wall or floor element.
Wie nachstehend im Einzelnen erläutert, kann das Eingießen insbesondere im Zuge der Herstellung des Wand- oder Bodenelements erfolgen, wenn dieses also bspw. aus Beton gegossen wird. Die Dichthülse kann dabei an einer Schalung montiert werden, anschließend ist sie baulich in das Wand- oder Bodenelement integriert. Das Vergussmaterial, typischerweise Beton, umschließt also die Dichthülse und hält sie in Position.As explained in detail below, the pouring can take place in particular in the course of the production of the wall or floor element, if this is, for example, poured from concrete. The sealing sleeve can be mounted on a formwork, then it is structurally integrated into the wall or floor element. The potting material, typically concrete, thus encloses the sealing sleeve and holds it in position.
Der vorliegenden Erfindung liegt das technische Problem zugrunde, eine besonders vorteilhafte Verwendung bzw. eine Dichthülse als Gegenstand der Verwendung anzugeben.The present invention is based on the technical problem of specifying a particularly advantageous use or a sealing sleeve as the object of use.
Dies wird erfindungsgemäß mit der Verwendung gemäß Anspruch 1 gelöst. Die entsprechende Dichthülse weist einen Vergussabschnitt und einen Stülpabschnitt auf, wobei letzterer während des Eingießens in den Vergussabschnitt eingestülpt ist. In diesem eingestülpten Zustand ist die Dichthülse axial kompakt, was bspw. ein Wand- oder Bodenelement mit vergleichsweise geringer Dicke erlaubt. Nach dem Eingießen wird der Stülpabschnitt ausgestülpt, und es wird durch den ausgestülpten Stülpabschnitt ein Rohr in die Dichthülse eingeschoben.This is achieved according to the invention with the use according to claim 1. The corresponding sealing sleeve has a potting section and an inverted section, the latter being turned into the potting section during casting. In this turned-in state, the sealing sleeve is axially compact, which, for example, allows a wall or floor element with a comparatively small thickness. After the pouring in, the everting section is turned out, and a tube is pushed into the sealing sleeve through the everted eversion section.
In seiner Endposition, also im fertig eingeschobenen Zustand, ist das Rohr solchermaßen in der Dichthülse platziert, dass eines seiner beiden Enden in der Dichthülse angeordnet ist. Das fertig eingeschobene Rohr erstreckt sich dann insofern zu seinem entgegengesetzten Ende aus der Dichthülse heraus (dieses entgegengesetzte Ende ist außerhalb der Dichthülse angeordnet). In den bzw. dem ausgestülpten Stülpabschnitt kann sich das Rohr bspw. gut einschieben und/oder befestigen lassen. Der ausgestülpte Stülpabschnitt kann bspw. mit einem Spannring, etwa einer Spannschelle, auf das eingeschobene Rohr angedrückt werden.In its end position, that is to say in the completely inserted state, the pipe is placed in the sealing sleeve in such a way that one of its two ends is arranged in the sealing sleeve. The completely inserted pipe then extends out of the sealing sleeve to its opposite end (this opposite end is arranged outside the sealing sleeve). The tube can, for example, be easily inserted and / or fastened into the everted everting section or section. The everted everting section can, for example, with a Clamping ring, such as a clamp, can be pressed onto the inserted pipe.
Bevorzugte Ausgestaltungen finden sich in den abhängigen Ansprüchen und der gesamten Offenbarung. Letztere unterscheidet nicht immer im Einzelnen zwischen den verschiedenen Anspruchskategorien, sondern betrifft stets sowohl Verfahrens- bzw. Verwendungsaspekte als auch Vorrichtungsaspekte. Wird bspw. das Eingießen der Dichthülse und Montieren des Rohres beschrieben, betrifft dies zugleich eine entsprechende Anordnung mit einer in ein Wand- oder Bodenelement eingegossenen Dichthülse, in die ein Rohr eingeschoben ist.Preferred configurations can be found in the dependent claims and the entire disclosure. The latter does not always differentiate in detail between the various claim categories, but always relates to both procedural and usage aspects as well as device aspects. If, for example, the casting of the sealing sleeve and mounting of the pipe is described, this also relates to a corresponding arrangement with a sealing sleeve cast into a wall or floor element, into which a pipe is inserted.
Der Vergussabschnitt ist jener Teil der Dichthülse, der nach dem Vergießen innerhalb des Wand- oder Bodenelements angeordnet ist. Die Dichthülse kann insbesondere solchermaßen in das Wand- oder Bodenelement eingegossen sein oder werden, dass sich der Vergussabschnitt über dessen Gesamtdicke erstreckt. Unabhängig davon legt sich das Vergussmaterial beim Eingießen bspw. an eine Außenwandfläche des Vergussabschnitts an. Der Stülpabschnitt ist hierbei eingestülpt, er kann z. B. an einer der Außenwandfläche radial entgegengesetzten Innenwandfläche des Vergussabschnitts anliegen. Dabei muss sich der eingestülpte Stülpabschnitt axial nicht über den gesamten Vergussabschnitt erstrecken, vergleiche auch das Ausführungsbeispiel zur Illustration. Das eingeschobene Rohr liegt dann mit einer Außenwandfläche an einer Innenwandfläche des ausgestülpten Stülpabschnitts an, vorzugsweise auch an einer Innenwandfläche des Vergussabschnitts.The potting section is that part of the sealing sleeve that is arranged within the wall or floor element after potting. The sealing sleeve can in particular be cast into the wall or floor element in such a way that the potting section extends over its entire thickness. Regardless of this, the potting material rests against an outer wall surface of the potting section, for example, during pouring. The everting section is here inversed, it can, for. B. abut against an inner wall surface of the potting section radially opposite the outer wall surface. In this case, the turned-in everted section does not have to extend axially over the entire potting section, compare also the exemplary embodiment for illustration. The inserted tube then rests with an outer wall surface on an inner wall surface of the turned-out inverted section, preferably also on an inner wall surface of the potting section.
In anderen Worten ist bzw. wird das Rohr in bevorzugter Gestaltung bis in den Vergussabschnitt eingeschoben, ist also das Ende des Rohres in der Endposition in dem Vergussabschnitt und damit innerhalb des Wand- oder Bodenelements angeordnet. Dies kann bspw. hinsichtlich der mechanischen Stabilität von Vorteil sein, das eingeschobene Ende wird in dem Wand- oder Bodenelement radial in Position gehalten (auch unabhängig von einer zusätzlichen Befestigung des Stülpabschnitts mit einem Spannring). Dies kann bspw. einem unbeabsichtigten Herausrutschen bzw. seitlichen Herauskippen des Rohres vorbeugen. Wenn sowohl der Stülp- als auch der Vergussabschnitt jeweils mit einer Innenwandfläche an dem Rohr anliegen, kann dies bspw. eine axial entsprechend große Dichtfläche zwischen Rohr und Dichthülse ergeben. In einem zur Axialrichtung senkrechen Schnitt betrachtet, liegt in dem Axialabschnitt, in den das Rohr eingeschoben ist, eine Innenwandfläche der Dichthülse an dem Rohr an und liegt an einer Außenwandfläche der Dichthülse das Vergussmaterial an (bspw. der Beton); da das Rohr aber nicht hindurchgeschoben ist, gibt es auch einen Axialabschnitt, in dem die Innenwandfläche nicht am Rohr anliegt.In other words, in a preferred configuration, the pipe is or is inserted into the potting section, that is to say the end of the pipe is arranged in the end position in the potting section and thus within the wall or floor element. This can be advantageous, for example, with regard to the mechanical stability, the pushed-in end is held radially in position in the wall or floor element (also independently of an additional fastening of the everting section with a clamping ring). This can, for example, accidentally slip out or prevent the pipe from tipping out to the side. If both the inverted section and the potting section each rest on the pipe with an inner wall surface, this can result, for example, in an axially correspondingly large sealing surface between the pipe and the sealing sleeve. Viewed in a section perpendicular to the axial direction, an inner wall surface of the sealing sleeve rests on the pipe in the axial section into which the pipe is inserted, and the potting material rests on an outer wall surface of the sealing sleeve (for example the concrete); but since the pipe is not pushed through, there is also an axial section in which the inner wall surface does not lie against the pipe.
Generell beziehen sich im Rahmen dieser Offenbarung "axial" und "radial" sowie "umlaufend", und die zugehörigen Richtungen (Axialrichtung etc.), auf eine Mittenachse der Dichthülse, die mittig in der von der Dichthülse begrenzten Durchgangsöffnung liegt. Bevorzugt ist bzw. wird die Dichthülse in ein Bodenelement eingegossen, liegt die Mittenachse also in Einbaulage vertikal. Je nach Einbaulage kann diese Mittenachse zu der bzw. den Seitenflächen des Wand- oder Bodenelements gewinkelt liegen, insbesondere rechtwinklig. "Nach innen" meint radial zu dieser Mittenachse hin, eine Innenfläche ist der Mittenachse zugewandt; "nach außen" meint radial von der Mittenachse weg, eine Außenfläche ist der Mittenachse abgewandt.In general, in the context of this disclosure, "axially" and "radially" as well as "circumferentially" and the associated directions (axial direction etc.) refer to a central axis of the sealing sleeve, which is located centrally in the through opening delimited by the sealing sleeve. Preferably, the sealing sleeve is or will be cast in a base element, so the center axis is vertical in the installed position. Depending on the installation position, this central axis can be angled to the side surface (s) of the wall or floor element, in particular at right angles. "Inward" means radially towards this central axis, an inner surface faces the central axis; "Outward" means radially away from the central axis, an outer surface faces away from the central axis.
Die Dichthülse kann bspw. eine Stegdichtung aufweisen, die in dem Vergussabschnitt angeordnet ist und sich gegenüber dessen Außenwandfläche nach radial außen erhebt. Vorteilhaft ist eine zwischen den axialen Enden des Vergussabschnitts angeordnete, also zu diesen Enden jeweils beabstandete Stegdichtung, welche dann von dem Vergussmaterial umschlossen wird (was Kriechwege entlang der Außenwandfläche verlängert bzw. blockiert). "Umschließen" meint insofern, dass in einem Axialschnitt betrachtet (Schnittebene beinhaltet Mittenachse) axial beidseits der Stegdichtung Vergussmaterial angeordnet ist. In dem Axialschnitt betrachtet kann die Stegdichtung einen oder mehrere axiale Vorsprünge haben, also mit dem Vergussmaterial einen radialen Hinterschnitt bilden (was eine Fixierung bzw. Verankerung schafft).The sealing sleeve can, for example, have a web seal, which is arranged in the potting section and rises radially outward with respect to its outer wall surface. A bar seal arranged between the axial ends of the potting section, that is to say at a distance from these ends, is advantageous, which is then enclosed by the potting material (which extends or blocks creepage paths along the outer wall surface). "Enclosing" means that, viewed in an axial section (section plane includes center axis), potting material is arranged axially on both sides of the bar seal. Viewed in the axial section, the bar seal can have one or more axial projections, that is to say form a radial undercut with the potting material (which creates a fixation or anchoring).
Wie vorstehend erwähnt, kann der Stülpabschnitt verringerte axiale Bautiefen ermöglichen. Das Wand- oder Bodenelement kann in bevorzugter Ausgestaltung eine Dicke von höchstens 200 mm, 180 mm, 160 mm, 140 mm, 120 mm, 110 mm, 100 mm bzw. 90 mm haben. Mögliche Untergrenzen, die auch unabhängig von einer Obergrenze von Interesse sein können und offenbart sein sollen, können bspw. bei mindestens 50 mm, 60 mm bzw. 70 mm liegen. Im Falle des Ausführungsbeispiels liegt die Dicke bspw. bei 80 mm. Entsprechend reduzierte Dicken können bspw. wegen der Materialersparnis und bei Fertigbetonteilen auch wegen des Gewichts von Vorteil sein. Die Dicke wird senkrecht zu den einander entgegengesetzten Seitenflächen des Wand- oder Bodenelements, zwischen diesen genommen.As mentioned above, the everting section can enable reduced axial structural depths. In a preferred embodiment, the wall or floor element can have a thickness of at most 200 mm, 180 mm, 160 mm, 140 mm, 120 mm, 110 mm, 100 mm or 90 mm. Possible lower limits, which can also be of interest and should be disclosed independently of an upper limit, can be, for example, at least 50 mm, 60 mm or 70 mm. In the case of the exemplary embodiment, the thickness is 80 mm, for example. Correspondingly reduced thicknesses can be advantageous, for example, because of the material savings and, in the case of precast concrete parts, also because of the weight. The thickness is taken perpendicular to the opposite side surfaces of the wall or floor element, between them.
Generell kann zwischen dem Verguss- und dem Stülpabschnitt die radial genommene Wanddicke der Dichthülse bspw. lokal reduziert sein, was das Stülpen des Stülpabschnitts vereinfachen kann. Die Dichthülse kann zwischen dem Verguss- und dem Stülpabschnitt bspw. als Filmscharnier ausgebildet sein. Generell sind der Verguss- und der Stülpabschnitt bevorzugt einstückig miteinander ausgebildet, also nicht zerstörungsfrei voneinander trennbar. Im Allgemeinen könnten die beiden bspw. auch als Mehr-Komponenten-Spritzgussteil hergestellt werden, könnte also bspw. der Vergussabschnitt aus einem härteren Material als der Stülpabschnitt vorgesehen sein. Bevorzugt sind die beiden monolithisch miteinander, also aus demselben, unterbrechungsfrei durchgehenden Material geformt (ohne Materialgrenze dazwischen). Jedenfalls der Stülpabschnitt, bevorzugt auch der Vergussabschnitt, kann aus einem Elastomermaterial vorgesehen sein.In general, the radially taken wall thickness of the sealing sleeve can be reduced, for example locally, between the potting section and the eversion section, which can simplify the eversion of the eversion section. The sealing sleeve can be designed, for example, as a film hinge between the potting section and the everting section. In general, the potting section and the everting section are preferably designed in one piece with one another, that is to say they cannot be separated from one another in a non-destructive manner. In general, the two could, for example, also be produced as a multi-component injection-molded part, that is to say, for example, the potting section could be provided from a harder material than the everting section. The two are preferably formed monolithically with one another, that is to say from the same, uninterrupted continuous material (without a material boundary in between). In any case, the everting section, preferably also the potting section, can be provided from an elastomer material.
Das "Elastomermaterial" ist ganz allgemein ein Kunststoff mit elastischem Verhalten. Dessen Shore-Härte (Shore A) kann bspw. bei höchstens 90 Shore, 80 Shore, 75 Shore bzw. 70 Shore und (davon unabhängig) bspw. bei mindestens 20 Shore, 25 Shore, 30 Shore, 35 Shore bzw. 40 Shore liegen. Es kann sich bspw. um ein Kautschukmaterial handeln, vorzugsweise um einen Synthesekautschuk, etwa EPDM (Ethylen-Propylen-Dien, M-Gruppe). Ebenso kann es sich aber bspw. auch um einen Thermoplastischen Elastomer (TPE) oder ein Silikonbasiertes Material handeln, etwa Silikonkautschuk bzw. Silikonelastomer. Das Rohrelement kann bspw. eine Shore-Härte (D) von mindestens 50 Shore, 60 Shore bzw. 70 Shore haben, mit möglichen Obergrenzen bei höchstens 85 Shore bzw. 80 Shore, jedenfalls im Falle von Kunststoff.The "elastomer material" is generally a plastic with elastic behavior. Its Shore hardness (Shore A) can, for example, be at most 90 Shore, 80 Shore, 75 Shore or 70 Shore and (regardless of this) for example at least 20 Shore, 25 Shore, 30 Shore, 35 Shore or 40 Shore . It can be, for example, a rubber material, preferably a synthetic rubber, such as EPDM (ethylene-propylene-diene, M group). But it can be the same For example, it can also be a thermoplastic elastomer (TPE) or a silicone-based material, such as silicone rubber or silicone elastomer. The tubular element can, for example, have a Shore hardness (D) of at least 50 Shore, 60 Shore or 70 Shore, with possible upper limits of at most 85 Shore or 80 Shore, at least in the case of plastic.
Gemäß einer bevorzugten Ausführungsform ist bzw. wird das Rohr bis zu einem Anschlag in die Dichthülse eingeschoben. Im Allgemeinen kann dazu bspw. auch an der Außenwandfläche des Rohres ein Vorsprung ausgebildet sein, der dann am axialen Ende des ausgestülpten Stülpabschnitts anliegt. Bevorzugt ist der Anschlag an der Innenwandfläche der Dichthülse ausgebildet, besonders bevorzugt in deren Vergussabschnitt. Der Anschlag kann zu den beiden axialen Enden des Vergussabschnitts bspw. jeweils um mindestens 10 %, 20 % bzw. 30 % der axialen Länge des Vergussabschnitts beabstandet sein.According to a preferred embodiment, the tube is or is pushed into the sealing sleeve up to a stop. In general, for this purpose, a projection can also be formed on the outer wall surface of the tube, for example, which then rests against the axial end of the turned-out everted section. The stop is preferably formed on the inner wall surface of the sealing sleeve, particularly preferably in its potting section. The stop can be spaced from the two axial ends of the potting section, for example by at least 10%, 20% or 30% of the axial length of the potting section.
Gemäß einer bevorzugten Ausführungsform ist in der Dichthülse eine Verschlussklappe angeordnet. Die Verschlussklappe kann bereits in der Dichthülse angeordnet sein, wenn diese in das Wand- oder Bodenelement eingegossen wird. Sie kann aber andererseits auch erst nachträglich eingesetzt werden, also in die bereits vergossene Dichthülse. Die Verschlussklappe kann die von der Dichthülse begrenzte Durchgangsöffnung verschließen, bspw. als Geruchs-, Ungeziefer- und/oder Schaumsperre. Die Klappe kann z. B. einstückig bzw. monolithisch in die Dichthülse eingeformt sein, es kann sich aber andererseits auch um ein gesondertes Bauteil handeln, das in die Dichthülse eingesetzt ist bzw. wird. Dieses Klappen-Bauteil kann bspw. die Klappe selbst und einen Klappenkörper aufweisen, an dem die Klappe gelagert ist. Der Klappenkörper kann eine Durchlassöffnung bilden, welche je nach Klappenstellung von der Klappe verschlossen oder freigegeben werden kann.According to a preferred embodiment, a closure flap is arranged in the sealing sleeve. The closure flap can already be arranged in the sealing sleeve when it is poured into the wall or floor element. On the other hand, however, it can also only be used subsequently, i.e. in the sealing sleeve that has already been cast. The closure flap can close the passage opening delimited by the sealing sleeve, for example as an odor, vermin and / or foam barrier. The flap can, for. B. be molded in one piece or monolithically in the sealing sleeve, but on the other hand it can also be a separate component that is or is inserted into the sealing sleeve. This flap component can, for example, have the flap itself and a flap body on which the flap is mounted. The flap body can form a passage opening which, depending on the flap position, can be closed or released by the flap.
Zur Positionierung bzw. Halterung des Klappen-Bauteils können an der Innenwandfläche der Dichthülse bspw. Haltemittel ausgebildet sein, die das Klappen-Bauteil axial in Position halten. Das Klappen-Bauteil kann bspw. in einer umlaufenden Nut positioniert sein bzw. werden. Die Dichthülse, deren Materialeigenschaften hinsichtlich einer guten Stülpbarkeit des Stülpabschnitts gewählt sind, kann auch in dieser Hinsicht Vorteile bieten, nämlich ein gutes Einsetzen und Herausnehmen des Klappen-Bauteils (oder auch anderer Bauteile, siehe unten) erlauben, es ist bspw. auch ein Austausch des bzw. der Bauteile bei eingegossener Dichthülse möglich.For positioning or holding the flap component, for example, holding means can be formed on the inner wall surface of the sealing sleeve, which hold the flap component axially in position. The flap component can, for example, in a circumferential Be or will be positioned groove. The sealing sleeve, the material properties of which are selected with regard to good reversibility of the everting section, can also offer advantages in this regard, namely allow easy insertion and removal of the flap component (or other components, see below); it is, for example, also an exchange of the component (s) is possible with a cast-in sealing sleeve.
Generell kann die Klappe bevorzugt kraftbeaufschlagt in der Schließstellung gehalten sein, z. B. bei entsprechender Lagerung von einem Gegengewicht oder von einem Federelement. Im Falle der einstückigen/monolithischen Klappe kann das Federelement mit angeformt sein, oder es kann ein gesondertes Federelement, z. B. ein Federring, eingesetzt werden, das die Klappe in die Schließstellung drückt. Unabhängig von diesen Details meint das Gehaltensein in der Schließstellung, dass die entsprechende Kraft (z. B. Feder- oder Gewichtskraft) die Klappe in jener Richtung beaufschlagt, in welcher die Klappe schließt. In der entgegengesetzten Richtung wird die Klappe geöffnet, z. B. von hindurchströmendem Wasser.In general, the flap can preferably be held in the closed position with force, e.g. B. with appropriate storage of a counterweight or a spring element. In the case of the one-piece / monolithic flap, the spring element can be molded on, or a separate spring element, e.g. B. a spring ring can be used, which presses the flap into the closed position. Regardless of these details, being held in the closed position means that the corresponding force (e.g. spring or weight force) acts on the flap in the direction in which the flap closes. In the opposite direction the flap is opened, e.g. B. of flowing water.
Generell kann die Klappe einerseits in einer Richtung schließen, die aus der Dichthülse durch das eingeschobene Rohr herausweist (von der zweiten zur ersten Seite des Wand- oder Bodenelements, siehe unten), das System ist dann für eine Strömungsrichtung von der ersten zur zweiten Seite ausgelegt (in dieser Richtung öffnet die Klappe). Die Klappe kann aber andererseits auch in einer über das eingeschobene Rohr in die Dichthülse weisenden Richtung schließen. Sie kann insofern eine Rückstauklappe darstellen, die zu dem eingeschobenen Rohr hin öffnet und von dem eingeschobenen Rohr weg schließt. Dieses System ist für eine Strömungsrichtung von der zweiten zur ersten Seite ausgelegt. Zusätzlich zu der Rückstaufunktion kann sie, insbesondere im Falle der Kraftbeaufschlagung in der Schließstellung, bspw. auch einen Geruchs- oder Ungezieferverschluss darstellen.In general, the flap can close on the one hand in a direction that points out of the sealing sleeve through the inserted pipe (from the second to the first side of the wall or floor element, see below), the system is then designed for a flow direction from the first to the second side (in this direction the flap opens). On the other hand, however, the flap can also close in a direction pointing over the inserted tube into the sealing sleeve. In this respect, it can represent a backflow flap which opens towards the inserted pipe and closes away from the inserted pipe. This system is designed for a flow direction from the second to the first side. In addition to the backflow function, it can also represent, for example, an odor or vermin seal, in particular when force is applied in the closed position.
Die Rückstauklappe wird von einer Strömung geöffnet, die von der zweiten Seite des Wand- oder Bodenelements, die der ersten Seite mit dem Stülpabschnitt entgegengesetzt liegt, durch die Dichthülse in das eingeschobene Rohr führt. Die Dichthülsenanordnung kann insofern bspw. zur Entwässerung genutzt werden, also um von der zweiten Seite des Wand- oder Bodenelements Wasser abzuführen. Kommt es bspw. bei einer Überlastung des Rohrleitungssystems, von dem das eingeschobene Rohr ein Teil ist, zu einer Rückstausituation, schließt die Rückstauklappe und kann eine Flutung der zweiten Seite des Wand- oder Bodenelements verhindert werden.The non-return flap is opened by a flow that is opposite to the second side of the wall or floor element and that of the first side with the everting section is through the sealing sleeve into the inserted pipe. In this respect, the sealing sleeve arrangement can be used, for example, for drainage, that is to say in order to remove water from the second side of the wall or floor element. If, for example, the pipeline system, of which the inserted pipe is a part, is overloaded, a backflow situation occurs, the backflow flap closes and flooding of the second side of the wall or floor element can be prevented.
Gemäß einer bevorzugten Ausführungsform ist in der Dichthülse ein Sieb angeordnet. Das Sieb könnte im Allgemeinen einstückig in die Dichthülse eingeformt sein, bevorzugt handelt es sich um ein Bauteil, das gesondert eingesetzt ist bzw. wird. Es wird auf die vorstehenden Anmerkungen zu einem "Bauteil" verwiesen, das Sieb kann bspw. an an der Innenwandfläche ausgebildeten Haltemitteln axial formschlüssig gehalten sein, bspw. in einer umlaufenden Nut. Ein eingesetztes Sieb lässt sich bedarfsweise entnehmen, bspw. zur Reinigungszwecken (des Siebs selbst oder des Rohrleitungssystems). In der Dichthülse können axial aufeinanderfolgend auch mehrere Siebe angeordnet sein, bspw. ein Grobsieb für Laub und ein Feinsieb für kleinere Verschmutzungen bzw. Einspülungen. Bezogen auf die vorstehend geschilderte Entwässerungsfunktion kann das Grobsieb bspw. näher an der zweiten Seitenfläche platziert sein als das Feinsieb (sodass es bei der Entwässerung zuerst durchströmt wird).According to a preferred embodiment, a sieve is arranged in the sealing sleeve. The sieve could generally be molded in one piece into the sealing sleeve; it is preferably a component that is or will be used separately. Reference is made to the above comments on a “component”; the sieve can, for example, be held in an axially form-fitting manner on holding means formed on the inner wall surface, for example in a circumferential groove. An inserted sieve can be removed if necessary, e.g. for cleaning purposes (of the sieve itself or of the pipeline system). A plurality of sieves can also be arranged axially one after the other in the sealing sleeve, for example a coarse sieve for leaves and a fine sieve for small amounts of dirt or debris. In relation to the dewatering function described above, the coarse screen can, for example, be placed closer to the second side surface than the fine screen (so that it is flowed through first during dewatering).
Generell ist das eingeschobene Rohr bevorzugt Teil eines Rohrleitungssystems, ist es also seinerseits mit einem weiteren Rohr zusammengesetzt (auf der ersten Seite des Wand- oder Bodenelements). Das Rohrleitungssystems kann vorzugsweise ein Abwasser-Rohrsystem sein, welches besonders bevorzugt zur Entwässerung der zweiten Seite des Wand- oder Bodenelements genutzt wird (zum Abführen von Wasser von dort). Bei einer bevorzugten Variante kann das Rohrleitungssystems insofern in der Dichthülse enden. Diese bildet dann also einen Ablauf, und das Rohrleitungssystems ist an der zweiten Seite des Wand- oder Bodenelements nicht mit einem zusätzlichen Rohr verlängert.In general, the inserted pipe is preferably part of a pipeline system, so it is in turn assembled with a further pipe (on the first side of the wall or floor element). The pipe system can preferably be a sewage pipe system, which is particularly preferably used for draining the second side of the wall or floor element (for removing water from there). In a preferred variant, the pipeline system can end in the sealing sleeve. This then forms a drain, and the pipeline system is not extended with an additional pipe on the second side of the wall or floor element.
Bei einer alternativ bevorzugten Ausführungsform wird bzw. ist von der zweiten Seite des Wand- oder Bodenelements her jedoch ein Inspektionsrohr an die Dichthülse angesetzt. Dieses kann bspw. zumindest in einem Bereich eine jedenfalls transluzente, bevorzugt transparente Wand haben und einer Wasserstandskontrolle dienen. Das Rohrleitungssystem endet dann bevorzugt mit dem Inspektionsrohr, an dieses ist also seinerseits kein weiteres Rohr angesetzt. Die entsprechende Dichthülse kann dann bspw. ohne Rückstauklappe ausgeführt sein, sodass bei einer Rückstausituation das Wasser über die Dichthülse hinaus in dem Inspektionsrohr ansteigen kann.In an alternatively preferred embodiment, however, an inspection tube is or is attached to the sealing sleeve from the second side of the wall or floor element. This can, for example, have a translucent, preferably transparent wall at least in one area and serve to control the water level. The pipeline system then preferably ends with the inspection pipe, so no further pipe is attached to this in turn. The corresponding sealing sleeve can then be designed, for example, without a backflow flap, so that in a backflow situation the water can rise beyond the sealing sleeve into the inspection pipe.
Dies kann bspw. eine Wasserstandskontrolle erlauben, das Inspektionsrohr kann z. B. mit einer Skala ausgestattet sein. Die Variante bzw. Verwendung "Inspektionsrohr" kann insbesondere in einem Entwässerungssystem von Interesse sein, in dem mehrere Dichthülsen in einer vorliegend geschilderten Weise Einsatz finden, also jeweils einen Ablauf bilden und an dasselbe Rohrsystem angeschlossen sind. Ein Teil der Dichthülsen kann dann jeweils mit einer Rückstauklappe ausgestattet werden, eine oder mehrere der Dichthülsen können hingegen zu Überprüfungszwecken mit einem Inspektionsrohr versehen werden.This can, for example, allow a water level control. B. be equipped with a scale. The variant or use of "inspection pipe" can be of particular interest in a drainage system in which several sealing sleeves are used in the manner described here, that is, each form a drain and are connected to the same pipe system. Some of the sealing sleeves can then each be equipped with a backflow flap, but one or more of the sealing sleeves can be provided with an inspection pipe for inspection purposes.
Gemäß einer bevorzugten Ausführungsform ist zumindest eines der beiden einander entgegengesetzten Enden der Dichthülse beim Eingießen mit einem Deckel verschlossen, bevorzugt ist in jedes der beiden Enden jeweils ein Deckel eingesetzt. Bei dem Ende mit dem Stülpabschnitt ist bzw. wird der Deckel in den eingestülpten Stülpabschnitt eingesetzt, entsprechend wird er vor dem Ausstülpen herausgenommen. Im Falle des entgegengesetzten Endes, das an der zweiten Seite des Wand- oder Bodenelements liegt, kann der Deckel nach dem Herausnehmen bspw. ein Sieb freilegen oder kann er gegen ein Sieb ausgetauscht werden. Im Allgemeinen könnte an einem oder beiden Enden jeweils auch ein einstückig, insbesondere monolithisch, mit der übrigen Dichthülse geformter Verschluss vorgesehen sein, der dann bspw. entlang einer Sollbruchstelle ausgetrennt wird. Ein separat eingesetzter Deckel kann jedoch bspw. insoweit von Vorteil sein, als er eine höhere Stabilität bieten kann. Ein eingesetzter Deckel kann aus einem im Vergleich zur Dichthülse härteren Material gefasst sein, also bspw. die Dichthülse zuverlässig verschließen (Trittschutz) oder während des Eingießens auch abstützen.According to a preferred embodiment, at least one of the two opposite ends of the sealing sleeve is closed with a lid when pouring in, preferably a lid is inserted into each of the two ends. At the end with the everting section, the cover is or will be inserted into the everted everting section, correspondingly it is removed before the eversion. In the case of the opposite end, which lies on the second side of the wall or floor element, the cover can, for example, expose a sieve after being removed, or it can be exchanged for a sieve. In general, a one-piece, in particular monolithic, closure formed with the rest of the sealing sleeve could also be provided at one or both ends, which closure is then separated, for example, along a predetermined breaking point. A separately inserted cover can, however, be advantageous insofar as it can offer greater stability. An inserted lid can be made from an im Compared to the sealing sleeve, it must be made of a harder material, for example reliably closing the sealing sleeve (step protection) or also supporting it during pouring.
Bei einer bevorzugten Ausführungsform wird durch die Dichthülse an der zweiten Seite des Wand- oder Bodenelements anstehendes Wasser abgeführt. Dieses Wasser gelangt über die Dichthülse in das eingeschobene Rohr und damit bspw. in ein Abwasserrohrsystem. Das eingeschobene Rohr wird also als wasserführendes Rohr genutzt.In a preferred embodiment, water that is present on the second side of the wall or floor element is discharged through the sealing sleeve. This water reaches the inserted pipe via the sealing sleeve and thus, for example, into a sewage pipe system. The inserted pipe is used as a water pipe.
Die Erfindung betrifft auch eine Dichthülsenanordnung mit einem Wand- oder Bodenelement, in das eine Dichthülse eingegossen ist. Die Dichthülsenanordnung kann insbesondere im Zuge eines Verfahrens bzw. einer Verwendung nach einem der Ansprüche 1 bis 10 hergestellt worden sein, in den ausgestülpten Stülpabschnitt kann bspw. ein Rohr eingeschoben sein, es wird ausdrücklich auf die vorstehend offenbarten Merkmale verwiesen.The invention also relates to a sealing sleeve arrangement with a wall or floor element into which a sealing sleeve is cast. The sealing sleeve arrangement can in particular have been produced in the course of a method or a use according to one of claims 1 to 10; a tube, for example, can be inserted into the turned-out everted section; express reference is made to the features disclosed above.
Gemäß einer bevorzugten Ausführungsform handelt es sich bei der Dichthülsenanordnung um ein Betonfertigteil, wird die Dichthülse also z. B. in einem Fertigteilwerk eingegossen und wird das Wand- oder Bodenelement mit der eingegossenen Dichthülse zur Baustelle transportiert. Mit Blick auf ein Betonfertigteil kann die Möglichkeit der Dickenreduzierung des Wand- oder Bodenelements bspw. dahingehend von Vorteil sein, dass eine mit der verringerten Dicke einhergehende Gewichtsreduktion bspw. auch den Transport- und/oder Montageaufwand reduzieren kann.According to a preferred embodiment, the sealing sleeve arrangement is a precast concrete part. B. cast in a precast plant and the wall or floor element is transported with the cast sealing sleeve to the construction site. With regard to a precast concrete part, the possibility of reducing the thickness of the wall or floor element, for example, can be advantageous in that a weight reduction associated with the reduced thickness can, for example, also reduce the effort involved in transport and / or assembly.
Bei dem Betonfertigteil kann es sich im Allgemeinen bspw. auch um einen Balkon- oder Terrassenelement handeln, bevorzugt ist es jedoch als Lichtschacht ausgebildet. Dieser kann bspw. im Erdreich platziert und an einer Außenwand eines Gebäudes gesetzt werden, wobei in der Gebäudewand bspw. ein Fenster im Bereich des Lichtschachts angeordnet sein kann. Die Ablauffunktion, und insbesondere die Rückstausperrung, kann bzw. können insofern von Vorteil sein, als damit einer Ansammlung von Wasser in dem Lichtschacht und damit einem Wassereintritt in das Gebäude über das Fenster vorgebeugt werden kann.The precast concrete part can generally also be a balcony or terrace element, for example, but it is preferably designed as a light shaft. This can, for example, be placed in the ground and set on an outer wall of a building, with a window in the building wall, for example, being able to be arranged in the area of the light shaft. The drainage function, and in particular the backwater blocking, can or can be advantageous in that it is one Accumulation of water in the light shaft and thus water entry into the building via the window can be prevented.
Im Folgenden wird die Erfindung anhand eines Ausführungsbeispiels näher erläutert, wobei die einzelnen Merkmale im Rahmen der nebengeordneten Ansprüche auch in anderer Kombination erfindungswesentlich sein können und auch weiterhin nicht im Einzelnen zwischen den unterschiedlichen Anspruchskategorien unterschieden wird.The invention is explained in more detail below using an exemplary embodiment, with the individual features within the framework of the independent claims also being essential to the invention in other combinations and furthermore no distinction is made between the different claim categories in detail.
